Are you on Windows?
Is the application marked as DPI Aware as asked by PB?

>> Are you running wxWidgets version supporting high DPI, i.e., 3.2 or newer?
>> Is your application marked as (Per Monitor v2) DPI-aware? You can verify this using Task Manager, in tab Details, in column DPI Awareness which should read "Per-Monitor (v2)" (the column may not be displayed by default so may need to be added).
>> Did you close and reopen the application after changing the DPI (see the red warning in your screenshot)?
